I have a legacy Surefire 9N I'd like to rebuild/upgrade.

The 9N just needs a new battery pack to function, but apparently they no longer make them. I've searched a couple forums and they have several homemade solutions, I'd like something plug and play it that is possible.

I'd also like to get an LED head if such a thing is possible.

This is primarily for auld lang syne, it was the first big belt carried flashlight I used on patrol.

I tried to rebuild an original slim body/non turbo head 6P several years ago and never could find an LED that functioned to replace the P60, so that might give you an idea of my level of expertise.

Any help would be appreciated.
